In partnership with the Equality Campaign, the company also installed post boxes in their 26 Australian stores to encourage customers to send pro-equality messages to MPs ahead of parliament resuming this week.

“We’ve made it easy for Australians to take action, by sending a message to MPs and urging them to make marriage equality a reality when they return to Canberra,” Ben & Jerry’s Australia spokesperson Imogen Rugg said.

She said the company has been overwhelmed with the support for the campaign internationally and here in Australia.

“If you haven’t or can’t send a postcard, make sure you have your say—the fight for marriage equality won’t stop until same sex couples are extended the same civil rights as heterosexual couples,” she said.
